From your log, you've been looking around and instrumenting the install routine. The DEPMOD=echo in the modules_install call is likely the source of why you aren't seeing some files in the install phase. Or did you already rule that out ? We are re-creating the .dep with all modules taken into account with the depwrapper, which takes you back to your original question, if I'm not mistaken. Mark Hatle did a lot of work with the depmodwrapper, but as far as I can recall, nothing of the 2.6.x vintage was tested. I'd suggest that patches against depmodwrapper to use the right files for a kernel of that vintage would be possible, but I'm not aware of anyone working on them at the moment.
